This was one of the most difficult pieces I've ever done. The pencil version was extremely large for one of my drawings (done on 2 11x17 sheets taped together in back), and had to have enough detail to look good even when clipped out into small sections, which is how it was used in the book. I don't think I did a good job getting the values to feel good in the scan (it's supposed to read as a silhouette and the interior detail should be secondary), but the printers got it right in the book, so I guess that's what matters.
